Welcome to the Community, @CRose1. We'll provide details about price rules and level inside QuickBooks Desktop (QBDT).
Know that we recognize how having the option to automate these features can help you save time. Upon checking here on our end, the option to add another two price rules inside the program is unavailable, and there's no option to change the cost if you're using it for a specific customer. That said, QBDT doesn't have a built-in feature to accomplish tasks like these and directly set up different levels of item cost based on the price level your customer is using.
As a workaround, you can utilize a third-party app that can help perform intricate tasks like these. Feel free to visit our official app store: https://desktop.apps.com/home
Furthermore, here's an article to help you manage price levels, price rules, and ensure your data stays accurate inside the program:
Thanks for dropping by here today, @CRose1. You can inform us in the comment section if you need further assistance with this or have any additional concerns related to QuickBooks. Stay safe, and have a good one.
